How to Use Robots.txt Generator

  1. Choose a 1-click Preset (Standard Production, AI Bot Opt-Out Shield, WordPress/WooCommerce, Next.js/React SPA, or Staging Disallow All) or create custom crawler blocks.
  2. Configure User-Agent groups for specific crawlers (Googlebot, Bingbot, GPTBot, ClaudeBot, Applebot, or All Bots *).
  3. Add Allow and Disallow relative URL path directives with optional wildcards (* and $).
  4. Set optional Crawl-Delay throttles (e.g. 1s, 2s, 5s) and attach one or more XML Sitemap URLs.
  5. Test relative URL paths in the Real-Time RFC 9309 Indexability Simulator to verify if specific pages are allowed or blocked for different search bots.
  6. Copy the clean robots.txt directives to clipboard, upload an existing file to edit, or download the formatted robots.txt file to place in your website root directory.

Crawl Budget Optimization & Technical SEO Architecture

Crawl budget refers to the number of URLs search engine bots can and want to crawl on your site within a given timeframe. Restricting crawler access to low-value, duplicate, or internal utility pages (such as facet filters, checkout funnels, staging previews, and admin panels) preserves crawl budget for your high-priority commercial and content pages.

Essential Security Warning: Robots.txt is Not Access Control

Robots.txt is a publicly accessible, plaintext document readable by anyone on the web. Never list confidential endpoints, unlisted staging URLs, or secret admin login paths in robots.txt as a security measure, as malicious scrapers actively read robots.txt to discover hidden directories. Use HTTP authentication, IP allowlists, and firewall rules to protect private areas.

Frequently Asked Questions

Where must the robots.txt file be uploaded on a website?
The robots.txt file must reside in the top-level root directory of your website host (e.g., https://example.com/robots.txt). Search engine crawlers only query this exact root URL; placing it inside a subdirectory (such as /assets/robots.txt) will cause crawlers to ignore it completely.
How do I block AI web crawlers (like OpenAI GPTBot and Anthropic ClaudeBot) without hurting Google Search rankings?
You can create dedicated User-agent directive blocks specifically targeting AI bots without modifying your primary Googlebot or general (*) rules. For example: User-agent: GPTBot Disallow: / User-agent: ClaudeBot Disallow: / User-agent: Google-Extended Disallow: / Disallowing Google-Extended prevents your content from being used in Gemini AI training while leaving standard Googlebot search indexing 100% active.
What is the difference between Robots.txt Disallow and the HTML noindex meta tag?
Disallow in robots.txt tells crawlers not to fetch or crawl the URL payload, but Google may still index the URL in search results if other websites link to it. In contrast, the tag allows the page to be crawled but explicitly commands search engines never to display the URL in search results. Never disallow a page in robots.txt if you want Google to see your noindex tag.
How does RFC 9309 longest-match rule priority work in robots.txt?
Under the official IETF RFC 9309 Robots Exclusion Protocol, when a URL matches multiple Allow and Disallow directives, the crawler selects the rule with the longest character string. If an Allow and a Disallow rule have the exact same character length, the Allow rule takes precedence.
Does Googlebot support the Crawl-delay directive in robots.txt?
No. Googlebot ignores the Crawl-delay directive because Google’s crawler dynamically adjusts its crawl rate based on your server’s response latency. However, Bingbot, Yandex, and Baidu still respect Crawl-delay (specified in seconds) to prevent server CPU overload.
Can I use wildcards (* and $) in robots.txt pathways?
Yes. The asterisk (*) matches any sequence of zero or more characters (e.g., `Disallow: /*?*sort=` blocks sorted query parameters). The dollar sign ($) marks the end of the URL pattern (e.g., `Disallow: /*.pdf Robots.txt Generator | Create & Test SEO & AI Crawler Rules Robots.txt Generator | Create & Test SEO & AI Crawler Rules blocks all PDF files while allowing URLs like /file.pdf.html)." } } ] }, { "@type": "Organization", "@id": "https://www.toolique.in/#organization", "name": "Toolique", "url": "https://www.toolique.in", "logo": "https://www.toolique.in/favicon-512x512.png", "foundingDate": "2026-06-16", "description": "Toolique is a premium, free, privacy-focused online suite of interactive calculators, developer converters, and programming academy tools operating completely in the browser.", "contactPoint": { "@type": "ContactPoint", "contactType": "customer support", "email": "support@toolique.in" }, "founder": { "@type": "Person", "@id": "https://www.toolique.in/about-founder#person" }, "sameAs": [ "https://github.com/ajinkyaswami1999", "https://www.linkedin.com/in/ajinkya-swami-82751b191/", "https://www.instagram.com/ajinkyaswami.in/", "https://voxelique.com", "https://www.instagram.com/voxelique/" ] }, { "@type": "Person", "@id": "https://www.toolique.in/about-founder#person", "name": "Ajinkya Swami", "jobTitle": "Founder & Software Architect", "image": "https://www.toolique.in/favicon-512x512.png", "description": "Ajinkya Swami is a QA Automation Engineer, Full-Stack Developer, and founder of Toolique and Voxelique, specializing in custom desktop automation script systems and web application development.", "worksFor": { "@type": "Organization", "@id": "https://www.toolique.in/#organization" }, "founderOf": [ { "@type": "Organization", "@id": "https://www.toolique.in/#organization" } ], "knowsAbout": [ "Software QA Verification", "QA Automation Frameworks", "Python & Selenium Models", "React & Next.js Stacks", "3D Printing Custom Design Solutions" ], "sameAs": [ "https://github.com/ajinkyaswami1999", "https://www.linkedin.com/in/ajinkya-swami-82751b191/", "https://www.instagram.com/ajinkyaswami.in/", "https://voxelique.com", "https://www.instagram.com/voxelique/" ] }, { "@type": "WebSite", "@id": "https://www.toolique.in/#website", "name": "Toolique", "url": "https://www.toolique.in", "publisher": { "@type": "Organization", "@id": "https://www.toolique.in/#organization" }, "potentialAction": { "@type": "SearchAction", "target": "https://www.toolique.in/tools?q={search_term_string}", "query-input": "required name=search_term_string" } } ] } blocks all PDF files while allowing URLs like /file.pdf.html).
